Mohandesi refactored tunnel establishment in the hectorqin/outline-client repository, unifying the use of outline.Client for both TCP and UDP tunnels. By consolidating tunnel creation to rely on a single client instance, Mohandesi reduced dependency complexity and improved the consistency of network traffic handling across protocols. The work focused on client-server architecture and network programming in Go, emphasizing maintainability and testability. This architectural change simplified resource management and made the codebase easier to extend and review. Although no external bugs were reported, the refactor enhanced code readability and reliability, demonstrating thoughtful application of refactoring principles to streamline tunnel wiring.
